Ecological conditions, especially in large cities, active urbanization and the COVID-19 pandemic reinforced the importance of architecture, which exterior and interior both care about the human health, taking into consideration the influence of architectural forms on physical, mental and socio-cultural states of a person being around those structures, living in them or using them on a daily basis. The article clarifies the methodological foundations and conceptual apparatus of design, which can be referred to as the “healthy” architecture meaning it is aimed at maintaining the health of its users. The author refers to concepts of “healthy”, “sustainable” and “living” architecture, biomorphic approach and biophilia. It is implemented not only in the material environment (i.e. objectively) but also as an architect’s design setting, the design algorithms that are being used today require a change towards greater individualization of the form. It is dictated, on the one hand, by the characteristics of users and, on the other hand, by the natural and social context.
